An efficient algorithm for ogee spillway discharge with partiallyopened radia...theijes
Ogee profile flood spillways equipped with radial gates are common, and accurate computation of spilled discharge through partially-opened radial gates is an important problem. A new algorithm is developed for the method given in the latest edition of the book: Design of Small Dams for computation of discharge over ogee spillways equipped with radial gates for the partial opening case. This algorithm is more efficient with less computational load than the one presented in ‘Hydraulic Design Criteria, Sheets 311-1 to 311-5’ by US Army Corps of Engineers which is the method by ‘Design of Small Dams’. For a wide range of partial gate openings on a few existing dams, discharges are computed by this method and are compared with those given by the previous method comprised in the former editions of ‘Design of Small Dams’. As both yield close values for small gate openings, the current method gives spillway discharges about 10 % to 30 % greater than the previous method for large gate openings. Next, discharge coefficients are computed using the measured data taken on 1:50 scale laboratory model of the spillway of Kavsak Dam and are compared with those given by the charts in ‘Design of Small Dams’, which are found to be deviant as much as 10 %.
A Wear Map for Recip Compressor PerformanceLuis Infante
Perfomance curves for recip compressor are usually, if not always, constructed in as new condition. But, what happens when seals deteriorate with time?. Can one use OEM performance curves to control unhealthy cylinders?. Surely and only for orientation purposes, as a reference point.
Updating performance maps according to accumulated wear can help field operators and analysts to estimate the recommended Variable Volume Clearance Pockets (VVCP) settings due to changing process conditions (Ps, Pd) and to match flow readings either from electronic analyzers or meters.
Accumulated wear moves (downwards) the power and flow curves thus disabling the "as new" VVCP curve.
The governing criteria for this analysis is that, as running time degrades compressor performance, the volumetric efficiencies (VEs) drop due to increasing leakages in the seals. Certainly, degraded VEs can be obtained with the electronic analyzer. On the other hand, as new VEs can be obtained either from electronic analyzers or from constant VE maps as shown in this analysis.
Here you will find a practical quasi-empirical approach to quantify wear in both engine and compressor side, and to depict a wear map with the help of an in-house compresser modeller.
At its own, engine wear appears easier to handle with the help of either a combustion pressure or static (cold) compression indicator.
Preliminary criteria for establishing alarm and trip levels is provided.

CFD and Artificial Neural Networks Analysis of Plane Sudden Expansion FlowsCSCJournals
It has been clearly established that the reattachment length for laminar flow depends on two non-dimensional parameters, the Reynolds number and the expansion ratio, therefore in this work, an ANN model that predict reattachment positions for the expansion ratios of 2, 3 and 5 based on the above two parameters has been developed. The R2 values of the testing set output Xr1, Xr2, Xr3, and Xr4 were 0.9383, 0.8577, 0.997 and 0.999 respectively. These results indicate that the network model produced reattachment positions that were in close agreement with the actual values. When considering the reattachment length of plane sudden-expansions the judicious combination of CFD calculated solutions with ANN will result in a considerable saving in computing and turnaround time. Thus CFD can be used in the first instance to obtain reattachment lengths for a limited choice of Reynolds numbers and ANN will be used subsequently to predict the reattachment lengths for other intermediate Reynolds number values. The CFD calculations concern unsteady laminar flow through a plane sudden expansion and are performed using a commercial CFD code STAR-CD while the training process of the corresponding ANN model was performed using the NeuroShellTM simulator.

WEB APPENDIX 5A
CALCULATING BETA COEFFICIENTS
5A-1
The CAPM is an ex ante model, which means that all of the variables represent be-
fore-the-fact, expected values. In particular, the beta coefficient used in the SML
equation should reflect the expected volatility of a given stock’s return versus the
return on the market during some future period. However, people generally calculate
betas using data from some past period, and then assume that the stock’s relative
volatility will be the same in the future as it was in the past.
To illustrate how betas are calculated, consider Figure 5A-1. The data at the bot-
tom of the figure show the historical realized returns for Stock J and for the market
over the last five years. The data points have been plotted on the scatter diagram, and
a regression line has been drawn. If all the data points had fallen on a straight line,
as they did in Figure 5-9 in Chapter 5, it would be easy to draw an accurate line.
If they do not, as in Figure 5A-1, then you must fit the line either “by eye” as an ap-
proximation or with a calculator.
Recall what the term regression line, or regression equation, means: The equation Y �
a � bX � e is the standard form of a simple linear regression. It states that the de-
pendent variable, Y, is equal to a constant, a, plus b times X, where b is the slope co-
efficient and X is the independent variable, plus an error term, e. Thus, the rate of
return on the stock during a given time period ( Y ) depends on what happens to the
general stock market, which is measured by X � k
–
M.
Once the data have been plotted and the regression line has been drawn on graph
paper, we can estimate its intercept and slope, the a and b values in Y � a � bX. The
intercept, a, is simply the point where the line cuts the vertical axis. The slope coef-
ficient, b, can be estimated by the “rise-over-run” method. This involves calculating
the amount by which k
–
J increases for a given increase in k
–
M. For example, we ob-
serve in Figure 5A-1 that k
–
J increases from �8.9 to �7.1 percent (the rise) when k
–
M
increases from 0 to 10.0 percent (the run). Thus, b, the beta coefficient, can be mea-
sured as follows:
Note that rise over run is a ratio, and it would be the same if measured using any two
arbitrarily selected points on the line.
The regression line equation enables us to predict a rate of return for Stock J,
given a value of k
–
M. For example, if k
–
M � 15%, we would predict k
–
J � �8.9% �
1.6(15%) � 15.1%. However, the actual return would probably differ from the pre-
dicted return. This deviation is the error term, eJ, for the year, and it varies randomly
from year to year depending on company-specific factors. Note, though, that the
higher the correlation coefficient, the closer the points lie to the regression line, and
the smaller the errors.
In actual practice, monthly, rather than annual, returns are generally used for k
–
J
and k
–
M, and five years of data are.

RESUMEN EJECUTIVO
El propósito de este informe es proporcionar un sitio alternativo para el proyecto hidroeléctrico binacional Dos Bocas propuesto por la República Dominicana y establecer los parámetros operativos para cualquier proyecto hidroeléctrico planificado en la cuenca hidrográfica del Artibonito aguas arriba de Péligre. Dado que el estudio anterior no tuvo en cuenta el efecto de Dos Bocas en la operación de Péligre y tuvo que establecer estos parámetros operacionales (línea de base mínima), el embalse y la instalación hidroeléctrica de Péligre tuvieron que ser evaluados.
Por lo tanto, en este informe, se propone una ubicación alternativa para Dos Bocas que beneficiará enormemente a Peligre y aumentará la producción de energía para Dos Bocas y Peligre. Para completar este estudio y formular las recomendaciones operativas, se modeló una nueva "curva de regulación del embalse". En total, se realizaron más de 75 simulaciones operacionales de Péligre y Dos Bocas operando en cascada.
Este informe y los documentos que lo acompañan apoyan las conclusiones de este estudio.
EXECUTIVE SUMMARY
The purpose of this report is to offer an alternate location for the Dos Bocas hydroelectric project as proposed by the Dominican Republic, and sets the operating parameters for any hydroelectric project planned within the Artibonite Watershed upstream of Peligre. The previous study did not consider the effect of Dos Bocas to the operation of Peligre. In order to set these operational parameters, the Peligre reservoir and hydroelectric facility had to be evaluated to establish a minimum baseline. This report has evaluated these parameters and is proposing an alternate location for Dos Bocas that will greatly benefit Peligre, and increase the energy production for either Dos Bocas and Peligre. To complete this study and formulate the operational recommendations, a new “Reservoir Rule Curve” has been modelled. In total more than 75 operational simulations of Peligre and Dos Bocas operating in cascade have been performed. This report and back up documentations support the findings of this study.
SOMMAIRE EXÉCUTIF
Le but de ce rapport est d'offrir un site alternatif pour le projet hydroélectrique binational de Dos Bocas tel que proposé par la République Dominicaine et fixer les paramètres d'exploitation pour tout projet hydroélectrique prévu dans le bassin versant de l'Artibonite en amont de Péligre. L'étude précédente n'ayant pas tenu compte de l'effet de Dos Bocas sur le fonctionnement de Péligre et devant établir ces paramètres opérationnels (ligne de base minimale), le réservoir et l'installation hydroélectrique de Péligre ont dû être évalués.
Ainsi, dans ce rapport, il est proposé un autre emplacement pour Dos Bocas qui profitera grandement à Péligre et augmentera la production d'énergie pour Dos Bocas et Péligre. Pour compléter cette étude et formuler les préconisations opérationnelles, une nouvelle "courbe de régulation du réservoir" a été modélisée. Au total, plus de 75 simulations opérationnelles de Péligre et Dos Bocas fonctionnant en cascade ont été réalisées.
Ce rapport et les documents qui l'accompagnent appuient les conclusions de cette étude.
The hydroelectric potential of Haiti consists of 164 sites ranging from 50 KW to over 10,000 KW for a cumulative total of 225,478 KW. From the spatially spotted sites, 79 were deemed to be the most feasible based solely on a 20% or above for the ratio of the minimum power over the maximum power. The cumulative capacity of these 79 sites is approximately 168,969 KW

Understanding Inductive Bias in Machine LearningSUTEJAS
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.
We have compiled the most important slides from each speaker's presentation. This year’s compilation, available for free, captures the key insights and contributions shared during the DfMAy 2024 conference.

HYDPFL
Abstract:
This software evaluates any roadway given a profile, a PGL tie, and a constant or variable typical
section. The edge of pavement profile can be plotted to analyze low points or flat grades.
Additionally, elevations for any point within a given profile, and typical section can be calculated.
This software is mainly a tool to analyze vertical geometries.

PROFILE CROSS SECTION CALCULATOR
1.0 DESCRIPTION
The HYDPFL program was developed as a tool to help engineers quickly create a complete database
for a roadway project consisting of PGL-TIE, street profiles, and typical sections. An entire project
vertical geometry could be stored and evaluated by HYDPFL. Once all the vertical data have been
entered, any point defined by a station and offset that falls within a defined street; an elevation
value can be obtained.
The first step is to tie the Profile Grade Line (PGL) in relation with the roadway Centerline (CL). This
tie is defined by a set of distances at given stations. The PGL-CL tie is entered as linear geometry.
For the case of variable curvy-linear geometry, tie distance at intermediate stations shall be
entered. The sign convention used for the PGL-CL tie distance is as defined in figure 1.
Figure 1: PGL-CL tie graphical representation.
Once the PGL-CL tie has been set up, the next step is to enter a project profile. A profile is defined
by vertical points entered by stations, elevations, and parabolic vertical curves length. A point
along a vertical curve is calculated by the following formula.
𝑦 = 𝑎𝑥2
+ 𝑏𝑥 + 𝑐
5. Francis Mitchell, M.S., P.E. PAGE 4
𝑎 =
𝐺2 − 𝐺1
2𝐿
𝑏 = 𝐺1
Where:
y = roadway elevation at distance x from the beginning of the vertical curve
x = distance from the beginning of the vertical curve
c = elevation of a point on the vertical curve
G1 = initial roadway grade in percent
G2 = final roadway grade in percent
Following the set-up of the vertical geometry, the final step is to define a typical section. The typical
section is entered by segments. Each segment is defined by a begin station, begin offset, begin
width, begin slope in percent, and by an end station, an end offset, an end width, an end slope in
percent. Begin and end offset are from CL. Begin and end slope are defined from CL, slope going
above horizontal is entered as positive, while slope going below horizontal is entered as negative.
These parameters are illustrated in figure 2.
